Alpha Invasion

Alpha Invasion is an 11-level invasion mappack for Doom II and the Skulltag source port, created by a team led by Robert Zalewski (Zalewa) and first released on March 14, 2007. It was one of the first invasion mappacks to be released in the aftermath of Skulltag implementing the gamemode, and it saw additional contributions by wario, Stuart Rynn (Forty-Two), and HeavenWraith. It also includes some new custom monsters, and a DeHackEd patch originally made by SuperGod to provide an increased ammo cap.

It received a sequel later that year, Delta Invasion, which also included updates to the maps from Alpha Invasion.
